Light travels through the eye by entering through the protective layer called the cornea (17). It then moves through the opening of the pupil which is surrounded by the iris (18), which is a muscle. It will then go through the transparent structure behind the pupil known as the (19) that changes shape to help focus images on the retina in a process known as (20) The retina contains the photoreceptors known as the (21) and (22). It is there that the actual process of transduction occurs when the photoreceptors excite the (23) cells which in turn send the message on to the (24) cells whose axons make up the optic nerve. The information will then travel to the (25), which is the sensory switchboard within the brain and end up in the (26) lobes where the information is processed specifically within the primary cortex (27).

Where can you find prokaryotic and eukaryotic cells?

(me out over the last several centuries, scientists have made the following broad observations while investigating several branches of the life sciences: -the fossil record shows that different types of organisms have existed at different times in earth's history. -many organisms have similar body structures that seem to be adapted to different ways of living in their environment. -organisms of different species often share similarities in stages of embryonic development. -many species share genetic similarities, and almost all organisms use the same basic building blocks to construct proteins. -often, the extent of two species' similarities can be predicted from their geographic closeness to each other. -a great deal of change has been observed among species that have experienced strong selective pressures through many generations. scientists have carefully considered and rigorously tested the observations listed above. when scientists offer a of these observations, they are making 1.) testable explanation, deductive explanation 2.) scientific interference, scientific law
